JAMES L. H AMILTON OF GRAND JUNCTION, COLORADO, ASSIGNOR TO THE HAMILTONORCHARD HEATER COMPANY,v OF GRAND JUNCTION, COLORADO, 'A CORPORATION OFWEST VIRGINIA.

To all whom it may concern:

Be it known that I, JAMES L. HAMILTON, a citizen of the United States,residing at Grand, J unct ion,'in the county of Mesa and State ofColorado, have invented a new 'and useful Improvement inOrchard-Heaters, of which the following is a specification. I

My invention relates to improvements in orchard heaters, beingparticularly directed to improvements in heaters of the sliding coverreservoir type which are adapted to burn liquid fuels derived frompetroleum, as shown and described in two patents issued to me, being'No.940,9fio issued November 23, 1909, and No. 970,044 issued September 13,1910.

. pended from the underside of the sliding The object of thisimprovement is to provide means for making the combustion of the fuel inthis type of heater more complete and perfect and eliminating'theproduction of smoke, which is undesirable in many 10- calities. I attainthis object by means of,

the mechanism shown in the accompanying The liquid fuel reservoir 5 ispreferably rectangular in shape, with tapering sides as shown, therebyallowing them to be closely packed or nested together for shipment andstorage. A sliding cover 6 is provided. It is securely retained on thereservoir by means of the rolled edges 4, but may be freely movedlongitudinally, thereby con- -trolling the admission of air for thecombustion of the fuel and thus regulating the rate of combustion andheat generated thereby.-

.A hinged partition or apron 7 is sus cover near its forward end. Thisapron is slightly smaller than the reservoir, and is provided withnumerous perforations 8. A draft chimney 9 is secured to the upper sideof the sliding cover directly over an open- Specification of LettersPatent.

ing therein, and just back of the hinged apron 7. This chimney ispreferably made.

tapering as shown and is provided with a.

row of perforations 10' near its upper end.

A cover 11 is provided. for the draft chimney 9 in order to preventtheentrance of rain or snow into the-fuel reservoir when the heater isstandingfin the orchard.

The heaters are distributed through the orchard or other tract it isdesired to protect from frost and nearly filled with the fuel oil. Thecovers are then closed 'until frost is threatened. "When a frost orfreeze is threatened the cover 11 is removed from the chimney and thesliding cover 6 is opened ashort distance as shown in Fig. 1. The fueloil is then lighted. Sufficient air to render the oil and gasescombustible enters through the opening at the end of the cover andpasses through the perforations 8 in the apron 7. The burning gasesascend through the chimney 9, where they are supplied with sutlicientair to consume the free 'a partition or apron containing numerousperforations suspended beneath the slidable cover near its front end,anopening in-said slidable cover located to the rear of said apron, anda draft chimney secured above said opening.
